Abstract
The resolution of a homodyne LADAR can be enhanced significantly by applying quantum optical techniques in the receiver. With a quantum image enhancer (QIE) inserted between the receive optics and the detector of a LADAR, an angular cell resolution improvement of 10x can be realized. The QIE is comprised of two key elements-a squeezed vacuum injector (SVI) that restores the high spatial frequencies lost by attenuation in soft-aperture entrance optics in the LADAR and a phase sensitive amplifier (PSA) that overcomes the inefficiency of the homodyne detector. When the QIE is combined with a phase-conjugate optical coherence tomographic (PC-OCT) technique for a two-fold range resolution enhancement, a 200-fold voxel (angle-angle-range) improvement is possible.
